To all whom it may concern:

Be it known that I, JOHN A. WERNER, a citizen of the United States, residing at Dayton, in the county ofMontgomery and State of Ohio, have invented certain new and useful Improvements in Cash-Registers, of which I declare the following to be a full. clear, and exact description.

This invention relates to cash registers and has for its main object to provide a device of the class mentioned which may be constructed at a low cost, but without sacrificing accuracy of operation or durability.

The mechanism as shown is ofthe socalled keyoperated type of machine, the

Among the main objects of the construetion are to provide an improved difierential mechanism comprising graduated frames and means for locking the frames at the end of the key stroke so as to prevent overthrow.

A further improvement comprises a novel construction of totalizer in which the elements are normally positively locked and are released only when they are to be operated or when a transfer is to take place, together with the provision ofimproved devices for engaging and disengaging the totalizer elements with their operating mechanism. The transfer mechanism also presents novelfeatures, it being of the type in which disks having cutaway portions are tripped by the totalizer elements and then are given a further movement to effect orv set directly and by the nearer ofthe two possible ways from a. preceding. to a subsequent position.

I A still further object is to provide an improved indicator operating construction With which the indicators are positively po sitioned by an operation of the keys and so as to move them directlyfrom one position to any other desired one without first returning the indicators to some intermediate positlon.

With these and incidental objects in View, the invention consists in certain novel features of construction and combinations of parts, the essential elements of which are set forth inappended claims, and a preferred form of embodiment of which is hereinafter described with reference to the drawings which accompanyand formpart of the speclficatlon.

Of said drawings: Figure 1 is a trans tical detail section showing the transfer operatlng devices and the operating rack of highest denomination. Fig. 3 is a detail verse vertlcal sectlon showing the characterlstic parts of the machlne. .F 1g. 2 1s a verfront elevation of the differential mechanism as a whole. Fig. l is a perspective de' line 66 of Fig. 7 showing one of thetotal izer elements and the transfer operating mechanism therefor. Fig. 6 is a view somewhat similar. to Fig. 6 showing the transferdevices partially operated. Fig. 7 is a front elevationof the totalizer and transfer mechanism. Fig. 8 is a section showing the zero resetting mechanism'for the totalizer. Fig. 9 is a detail of a cam forming part of the zero setting mechanism. Fig. 10 is a view showing the indicator operating devices; Fig. 11 is a detail showing the setting or positioningdevices for theindicator. Fig. 12 is a detail showing'the flash operating mechanism and certain lock actuating devices. Fig. l3 is a view of certain pawls employedfor locking the totalizer elements. Fig.' 14 is a view at right anglesto Fig. 13 showing the same pawls.

The mechanism herein described is of the general type known as key-operated, that is, the type in which the keys themselves di rectly furnish power for operating the rest ofithe mechanism. The keys are positioned ing connected to operate the transfer devices, to position the indicators and to actuate certain locking devices for various.

parts. The totalizer is composed of a series of elements of different denominations herein shown as cylinders, all being mounted in a pivoted frame whereby they may be thrown into and out of engagement wlth certain operating racks which have their motion directly determined by the keys. The totalizer elements are constructed to be positively locked at all times except when released to be actuated by the operating racks or by the transfer mechanism, this locking function being performed by certain locking pawls which are constructed to be withdrawn from the totalizer elements at the proper times.

The indicators as herein shown are of the well known rotary cylinder type, but they are adapted to be moved in either direction and by the shorter of the two possible routes, directly from a preceding to a subsequent position, without being reset to zero. To accomplish this function, an element having radiating arms is attached to each indicator and mechanism including a roller is constructed to be positioned and to operate against the radiating arms and thereby to set the indicator. With this general statement, the specific description may be taken up and reference will be first made to the differential mechanism.

I The keys, usual in this type of machine, are indicated by the numeral 1 and are mounted in banks on a rod 8 around which they move. The keys are all similar and. are provided attheir rear ends with upwardly extending portions 10, these portions being all similar and being adapted to engage the arms of graduated frames 3, one of which is shownseparately in Fig. 4, in order to produce a differential movement of said frames. As will be seen in Fig. 4 these frames are composed of a single piece of sheet metal stamped and bent to the required shape, comprising two upwardly extending arms having pivot holes therein and a series of steps 11 arranged in different positions together with an additional set of graded steps or graduations 45 which project downs wa'rdly. As seen in Fig. 1, the graduations 11 are directly over the upper ends 12 of the keys, the consequence being that when the keys are depressed the upper ends 12 thereof engage and rotate the graduated frames difierentially, depending on the keys depressed. The keys have all the same extent of stroke. This operation will: be evident from the drawings, but the downwardly extending graduations 45 provide an additional control whereby .to prevent overthrow of the graduated frames. It will be seen from Fig. 1 that the graduations 45 are arranged in a manner substantially the same as the graduations 11, that is, the distance between any one pair of graduations which cooperate with a particular key, is the same. From this construction it follows, that as the key rises, the rear edge 46 thereof, which is circular from the center of rod 8, will finally be'en'gaged by the corresponding graduation 45, at which time the frame 3 will be locked, inasmuch as a graduation of each set engages the rear edgeof the key. This locked position will be reached somewhat before the end of the key stroke and it is clear that during the remainder of the stroke the circular edge 46 will ride past the graduation of both sets.

Each of the graduated frames 3 is connected to a segment gear 4 one of which is well shown in Fig. 1. Referring to Fig. 3, the units graduated frame 3 is connected directly to the right-hand segment gear 4 and the tens frame 3 is connected directly to the next segment gear'4, from the right-hand. The dollars graduated frame 3 which is the third from the right in this figure is connected rigidly to a segment gear 16, but the movement of this gear is transmitted to a segment gear 4, the third from the right of the set of gears 4, through pinions 17 and 19 fast on a shaft 18. The object of this construction is merely to arrange the operating segment gears 4 closely together. N 0 complete bank of tens of dollars keys is shown, though one may readily be employed if desired. From Fig. 3 it will be seen that two camming elements 21 are provided and that in connection with one of them, a key 1 is shown. The shape of these cam elements 21 is well shown in Fig. 2'and it will be understood that in practice, a key will also engage the left-hand one of the two cams. These cams are rigidly mounted on a sleeve 22 surrounding the shaft 24 and rigidly fastened to this sleeve is a driving gear-segment 23. This segment is connected to drive the left-hand one of the operating segment gears 4- through pinions 25 and 27 rigidly mounted on a shaft 26. From this description it will be seen that there are four operating segment racks 4 provided to engage four separate totalizer elements, and that each of these is connected either directly or through intermediate gearing to graduated devices which are directly operated by the keys- Before passing to a description of the totalizer mechanism 6, a short reference may be'made to the key coupler, inasmuch as this has much to do with operating various parts of the machine. In this machine, the key coupler comprises two side arms 34 connected by a cross rod 32 and a rear bar 135, the whole frame being journaled loosely on a rod 35 slightly above and to the rear of the key supporting rod 8. Each key is provided with a notch 31 which'is adapted to surround the cross rod 32 of the coupler when the keys are operated. This mechanism is very readily understood, inasmuch as key coupler mechanism is well known in the art, and it will be readily evident that the depression of any key will serve to elevate the coupler and that any key may be made to complete the stroke of all keys which are started at the same time.

The totalizer mechanism as before stated comprises a series of denominational elements, all of which are mounted in a pivoted frame. Referring to Fig. 7, it will be seen that frame pieces 47 support the totalizer elements, each of which comprises a pinion 5, a numbered cylinder or wheel 53 and a transfer tripping disk 54. Each of the transfer tripping disks 54 has a projection stamped or bent out and indicated by numeral 76 these serving to trip the transfer mechanism as will be readily understood. The frame pieces 47 and consequently the whole totalizer mechanism is journaled on a rod 48 and is provided with a downwardly extending arm (see Fig. 5) and a rear wardly extending arm indicated by numeral 68. A segment 57 shown in this figure is journaled loosely on the key coupler shaft 35 and is connected to the cross-rod 32 of the key coupler so as to move rigidly therewith in both directions. Near the upper side of this segment 57, a flange 64 is bent up having a cutaway portion 65. Mounted in a convenient place on the totalizer. frame 47 as indicated at 62 is a pawl 60 having a downwardly extending end, normally resting in the cutaway portion of the flange 64 and having a forwardly extending end 61 normally resting on a shaft 51 in the totalizer frame, this shaft being a part of the transfer mechanism. A spring 69 is compressed between projecting parts of the rearward extension 68 of frame 47 and the downwardly extending end 59 of the pawl 60. The parts in Fig. 5 are shown in normal position and it will be clear that when the key coupler is elevated and the segments 57 rocked in the direction of the arrow 63 the flange 64 will engage the lower end 59 of pawl 60, and inasmuch as this pawl engages with the shaft 51 and is therefor immovable relative to the totalizer frame 47, it will rock the whole frame around its supporting rod 48 thereby moving the totalizer pinions 5 into engagement with the rack segments 4. This will be clear from a study of Figs. 1 and 2 wherein the totalizer elements and frame are shown in normal position and out of mesh with the operating segments 4. When the frame is so rocked, a roller on the downwardly extending part thereof is moved out side the path of flange 64 and rides thereon during the continued movement of the flange and segment 57. At the end ofthe forward movement of this segment, the-projection 67 thereon engages the rearward arm 68 of the totalizer frame and cams it upward as will be readily understood from Fig.5, thereby reversely rocking the totalizer frame around its rod 48 and withdrawing the pinions 5 from mesh with the operating segments. In this position of the parts, the withdrawing movement of the frame will not be prevented by the roller 70 as flange 64 has passed com: pletely under the said roller. Before the return movement of segment 57, that is, before the downward movement of the key coupler, the roller 70 will ride under the flange 64 and therefore prevent accidental rocking of the totalizer frame until the end of the rearward stroke of the parts is given,

at which time the pawl 60 will again be moved to a position such that its lower end 59 isin the cutaway portion 65 of the flange 64; It will be noted that during the back: ward stroke of segment 57, the pawl 60 may rockaround its pivot 62 so as tohave no effect on the totalizer frame.

. It was before stated that there are four segment racks 4 shown in the case, but it will be seen from Fig. 7 that six totalizer.

stamped and bent from a single piece of.

metal is provided and is shown in Fig. 5. This locklng dev ce comprises a forwardly extendlng arm 86 havlng a pro ection 87 an upwardly bent arm 88and a downwardly extending arm 865. As shown in this figure the locking piece is carried by the supporting rod 48 and also surrounds the shaft 18. It

will thus be seen that the locking piece is rigidly fast, inasmuch as neither rod 48 nor shaft 18 has any bodily movement. The upwardly extending projection 88 of this piece is so positioned as to be engaged by the totalizer. pinions 5 of the two highest denominations when the totalizer is thrown into engagement with the operating devices, so that these wheels are positively locked against operation at such time.

The transfer mechanism may be next referred to. The construction herein shown is suchthat the totalizer elements are locked at alltimes except when an operation should take place and this. locking is partly controlled by the transfer mechanism. In the device shown each totalizer element hasadjacent thereto a set of three starshaped devices, or devices having radiating points, one of each set being positioned to be engaged and moved bythe transfer tripping projection of the totalizer and also being adapted to be engaged and further rotated by a series of transfer operating disks. Another one of each set of three radiating elements is positioned to engage and operate the totalizer pinion of next higher order while the third starshaped element is constructed to be locked against operation by the said transfer controlling disks. One of these elements of each set is also adapted to control the totalizer' locking pawls. Referring to Figs. 6 and 7, these sets of disks are therein well shown. It will be seen from Fig. 7 that the star .77 of each set is in a position such that the tripping projection 76 of the totalizer elements will engage one of the projections and rotate the system or set of three stars onesixth of a complete rotation. This one-sixth movement does not cause any effect on the totalizer element of next higher order, but it does bring one of the projections of the element 77 into the path of an operating disk 52 or rather of a stamped out projection 79 thereof, so that when these disks, which have their operating projections successively or helically positioned, are given a rotation, the projections will engage all those stars which have been given a one-sixth rotation and will give them a second one-sixth rotation, this latter movement serving to efiect or turn in the transfer to the totalizer element of next higher order. To effect the transfer is the function of the star elements 80. It will be seen from Figs. 6 and 6 that a one-sixth rotation will bring one of the arms of this star into position such that on further movement it will engage the proper tooth of pinion 5 and move it one-tenth of a rotation, the further movement being as before stated given by the transfer orojection 79. The third disk or starshaped element 81 is provided to prevent a transferring movement of the set of stars until the proper time. It will be seen from the position of the star 81 of Fig. 6 that a one-sixth rotation will bring one of the arms thereof into engagement with the disk 52, thereby locking the set of star elements against any further movement, but when the transferring projection 79 of the proper disk 52 reaches the star 77 the cut away portion 83 of the disk 52 will then permit the projection of the star 81 to pass therein so that the second one-sixth rotation of the set of stars may be given. This clearly serves to prevent a transferring movement except by operation of the disks 52. In Fig. 6 are shown a series of pawls 89 j ournaled loosely on a shaft 90 carried in the totalizer frame 1 4:7. The downwardly extending portions 98 of these pawls are positioned to be engaged by projections of the stars 77 so that in the position of Fig. 6 the totalizer elements are positively locked. Clearly, however, when the stars are given a one-sixth rotation, the pawls will then be released so that the transfer may take place, but immediately after having taken place, the pawls are again restored to locking position. It will be noteld from Fig. 13 that these pawls are bent so that the upper operating ends thereof are in the plane of the next higher wheel. It is clearly necessary to release these pawls when the totalizer elements are to be actuated by the operating racks 4:, but as the whole system shown in Fig. 6 moves as a unit some additional mechanism must be provided to do this; this mechanism is shown in Figs. 9 and 1 1. It was stated that pawls 89 are mounted on a shaft 90 and from Fig. 14- as well as Fig. 18 it will be seen that shaft 90 is carried eccentrically by pins 91 to one of which is connected a crank arm 93 having a projecting pin 94. This pin 94; rides in a groove 95 of cam 96 as seen in Fig. 9. Under certain conditions the cam is adapted to be rotated but in ordinary operations of the machine, the cam stands still. From this'construction it will be clear that as the totalizer frame is moved upward to engage the pinions 5, a relative rotation of the pins 91 will be given, inasmuch as the projecting pin 94 rides in the cam groove 95 from the position shown in full lines inFig. 9 to that shown in dotted lines. The result of this movement clearly is, to withdraw shaft 90 from the totalizer mechanism and thereby to withdraw the pawls 89 sufliciently to permit operation of the totalizer pinions by the operating racks. As the totalizer sinks back to its withdrawn position the pawls again engage the totalizing wheels.

In order to reset the totalizer to zero position mechanism shown in Fig. 8 is provided. It was stated that the totalizer elements are mounted on the shaft 50 and this shaft as shown in Fig. 8 has a groove 100 in which rides a comb or notched plate 101, having notches 102 in which teeth 103 on the transfer disks 5 1 normally ride. Clearly, the ordinary rotary movement of the totalizer elements is not prevented as the depending teeth 103 ride in the annular grooves 103 in the shaft 50. If, however, the comb is moved longitudinally so as to bring the full projections between the notches 102 into the planes of the transfer disks, and the shaft 50 rotated, the totalizer elements will be picked up and restored to normal zero position by such rotation of the shaft. In order to give this rotation as stated, the comb 101 has a construction comprising a flat plate 106 and a bent projection 113 engaging in an annular groove 114 in 'a shaft 10 1. The shaft 104 has a plane surface 107 engaging the plate 106 so that rotationof the shaft 104 will cause an equivalent rotation of the plate 106 and consequently of comb 101 and shaft 50. In order to give the rotation to shaft 104 it is provided with a disk 105 which may be manually grasped, but-the shaft must be pushed slightly inward so as to move the comb 101 into position to coact with the totalizer elements. When so pushed inward the shaft may be given a complete rotation manually and the totalizer reset, after which a spring 112 engaging a disk 109 serves to push the shaft 101 to its normal outer position. The disk 109 is provided with a bent extension 108 engaging a camming plate 111 having a notch 110 as shown, so that the shaft 104 will be forced positively outward as it reaches its normal position after a rotation. It will be seen that cam 96 which was described in connection with the withdrawal of locking pawls 89 is mounted on this shaft 10 1 so that when the shaft is rotated the locking pawls 89 will be withdrawn from locking position precisely as they were when the totalizer frame was raised. This is clearly necessary as the totalizer elements could not be reset unless the pawls 89 were first withdrawn from looking position.

Passing now to the indicators and their operating devices it will be remembered that they were said to include rotary cylinders and mechanism for moving them by the vided with radial slots 119 in which rollers 120 ride. Clearly, as the keys are operated the segments 117 will be given differential movements equivalent in extent to the movement of the keys. The indicators are shown in Fig. 1 and indicated by numeral 6. They are all journaled loosely on a rod 127 and each has fast thereto a pinion 126 meshing with a large gear 7, and to each of these large gears is fast a star shaped element 123, the gears 7 and the star shaped elements being all loose on the rod 118 and positioned immediately beside the differential segments 117 before referred to. Slides 122 one for each bank of keys are carried on the rod 118 that the slides may move in an upwardly and forwardly direction. Each slide is provided with a slot 121 approximately circular from the rod 118 and the rollers 120 arealso the key coupler. When the keys are depressed and the coupler correspondingly elevated it will be clear that the segments 117 are differentially rotated, thus carryingthe rollers 120 through a portion of the circular slots 121. After these parts have been set to the desired differential position, the coupler bar135 engages the projections 136 on the slides 122 and gives the said slides a movement of an invariable extent. By this movement the rollers 120 are compelled to move in the radial slots 119 and will sooner or later engage some one of the radiating arms of the stars 123 and rotate the whole indicator system to the desired proper position. Clearly this mechanism provides for a movement in the shorter of two possible directions for the indicator and of only such extent as is necessary to cause the change from one exhibited number to another. During the reverse stroke of the keys, the coupler bar 135 engages the lower projections 1365 of the slides and returns said slides to their normal position, the differential segments 117 returning with the graduated frames 3 thereafter.

It is desirable to lock the indicatorsin their adjusted'positions, so as to prevent a false movement thereof, and it is also advantageous to lock the indicator controlling devices in any positions to which they may be moved by the keys, and during the movement of the indicators proper. To perform these two functions, mechanism shown 'in Figs. 10, 11 and 12 is provided. It will be evident that the indicators and theircontrolling segments are never simultaneously operating, as the segments must be set to determine the movement of the indicators, and because ofthis fact it is possible to employ a single set of elements to lock both the indicators and their controlling segments, by movement of said set of elements in opposite directions. These locking elements, as shown in Fig. 11, are indicated by numeral 139 and have each two locking parts. The indicator supporting shaft 12 rigidly carries all these elements (see Fig. 1), and they may be drawn in one direction by springs 1391. The forwardly extending arm of the locking elements have each a locking tooth 1392 which when the shaft 127 is rocked will engage the teeth 1 11 of the indicator controlling segments 117 and hold said segments while the indicators are being operated. Likewise, the rearwardly extending arms of locking elements 139 have cut therein saw teeth 1393, and thus the points of the indicator stars may be engaged by one of the saw teeth, no matter what position the star may assume, when the shaft 127 is rocked in a reverse direction. It will thus be seen that the locking of both the indicators and their controlling segments is accomplished by the movement in opposite directions of a single set of elements. To move these elements in one direction is the function of springs 1391, while their movement in the reverse direction is caused by the key coupler. Referring to Fig. 12 it will be seen that an arm 142 is fast on shaft 127, and that a lever 143 pivoted on rod 24 is joined to said arm, the lower end 144 of said lever being positioned to be engaged by a by-pass pawl 145 carried by the coupler and engaging the coupler back plate 135. When the coupler rises by depression of a key, the pawl 145 will engage the lower end 144 of said lever and rock said lever thereby causing the locking teeth 1392 of locking elements 139 to engage and hold segments 117 during the rise of slides 122 and the consequent setting of the indicators. When the coupler starts to return the pawl 145 will release the lever 143 and then the springs 1391 may reversely rotate the locking elements, thereby engaging the saw teeth 1393 with the points of the stars thus locking the indicators in adjusted positions and releasing the controlling segments 117.

The usual function of hiding the indicators during their movements may be performed by screens 146 (Fig. 12) pivoted loosely on shaft 127 and having pin and slot connections 148 to a link 149 which is car ried by slots surrounding shaft 127 and rod 118, reciprocated by a lever 151 journaled on rod 24 and having a pin and slot connection 152 with said link. The lower part of lever 151 has a slot 150 in which rides cross bar 32 of the key coupler, so that when the coupler moves the elements just described will be operated and the screens 146 will hide the indicators during their movements.

It was before stated that the transfer operating shaft 52 is given one rotation at each operation of the machine. To perform this function, a pinion 51 on one end of said shaft, see Fig. 2, is positioned to be engaged by a segment rack 74, this rack being mounted on rod 35 and having a rigid connection with the coupler cross bar 32. It will be clear from Fig. 2, showing the normal position of the parts, that when rack 74 moves forward by elevation of the coupler, pinion 51 would be engaged and rotated except for the fact that the whole totalizer frame, in which shaft 52 is carried, is elevated, to bring the totalizer elements into gear with the actuating segment racks 3, thus carrying inion 51 out of reach of the segment rack 4. Therefore, the forward movement of rack 74 produces no rotation of'pinion 51, but for the return of the coupler the totalizer frame is depressed, and thus during the backward movement of the rack 74, pinion 51 is engaged therewith and given a complete rotation. I It will be seen that this mechanism provides a simple but effective device for converting the two-direction movement of the rack into a uni-direction movement of the transfer shaft 52, and without the use of pawls or other easily derangeable mechanisms. The transfer shaft 52 requires motion in one direction only, but it might become displaced by elevation of the totalizer frame. To prevent this misoperation the plate 86, before referred to,

has a downwardly extending arm 87 positioned to be engaged by arms 84 and 85 (Fig. 5) of a plate carried fast by transfer shaft 52. Clearly, when the totalizer frame is elevated the plate arms 84 and 85 will surround locking arm 87 and the transfer shaft 52' will be prevented from rotation until the totalizer frame again descends. Thus accidental rotation of transfer shaft 52 is prevented.

' To restore the differential segments 3 to normal position positively, is the function of certain plates 37 shown in Fig. 1. These plates are carried loosely by rod 35 and have hooks 40 extending under the coupler cross bar 32. Each gear segment 3 is provided with a lug 39 above and a lug 38 behind the restoring plates 37. Thzus when any gear segment 3 is operated, its lug 38 will rock the corresponding plate 37 around its pivot rod 35. As the coupler returns to normal position the cross bar 32 will engage the hooks 40 of any displaced plates and positively restore them to normal position, thus engaging said plates with the lugs 38 of segments 3 and thereby positively returning the segments also to normal position. The upper lugs 39 prevent the gear segments from moving past zero position as projections 371 of plates 37 engage a stationary bar 372.
